(#2) Fix _diskpool_is_member() to return correct pool.

Verifying the volume exists isn't enough to prove the disk_pool struct is the
proper pool.  We need to verify the volume is in the pool of a given pool
struct.

Updates from 1 to 2:
  -Move the virStorageVolLookupByPath() call back to _diskpool_is_member() so
   that this fix is compatible with systems running libvirtd < 0.4.0.
